ADVERTISING ARM-CHAIR.

SPECIFICATION forming part of Letters Patent No. 576,054, dated January26, 1897. Application filed March 14, 1896. Renewed December 31, 1896.Serial No. 617,675. (No model.)

To all whom, it may concern.-

Be it known that I, LOUIS T. HAGAN, a citizen of the United States,residing at -Winchester, in the county of Clark and State of Ken- 5tucky,have invented new and useful Improvements in AdvertisingArm-Chairs, of which .the following is a specification.

This invention relates to that class of advertising mediums or deviceswhich are designed to be arranged in the arms of chairs for the purposeof displaying or exhibiting advertisements placed on a movable carriercomposed of a web of flexible material.

The chief object of the present invention I is to provide an advertisingarm-chair with new and improved means for effectually dis playing cards,signs, or other advertising matter, the construction being such that thecarrier bearing the advertisements is caused to travel whenever thechair-arm is depressed.

The invention also has for its object to provide a chair-arn1 with a webof advertisements which will be wound on a winding-roller and unwoundfrom an unwinding-roll to successively display advertising cards orsigns through a sight-opening in the chair-arm until a predeterminedtime, when the motion of the rollers is reversed and the web isintermittently rewound on the unwinding-roller and unwound from thewinding-roller.

The invention also has for its object to provide a chair with a pivotedchair-arm containing a web of advertisements, cards, signs, or otheradvertisements and mechanism whereby an intermittent motion is impartedto the web by the depression of the pivoted chairarm.

The invention also has for its object to provide new and improvedmechanism for reversing the motion of the advertising-web after it hasbeen unwound from one roller and wound on another roller.

To accomplish all these objects, my invention involves the features ofconstruction the combination or arrangement of parts, and the principlesof operation hereinafter described and claimed, reference being made tothe accompanying drawings, in Which- Figure 1 is a side elevation of anarm-chair provided with my invention. Fig. 2 is a dethe plane of sectionbeing on the line 4 4, Fig. 3.

Fig. 5 is a detail view of the gear-wheel, pinions, and pawl-trippinglever to more clearly illustratethe devices for reversing the motion ofthe advertising-web. Fig. 6 is a detail view showing the device forretaining the pawltripping lever in either position to which it isshifted for changing the direction of motion of the advertising-web, andFig. 7 is a detail plan view of the pawl-trippinglever and thereversing-pinion.

In order to enable those skilled in the art tomake and use my invention,I will now describe the same in detail, referring to the accompanyingdrawings, wherein The numeral 1 indicates the seat of the armchair, 2the chair-back, and 3 the front legframe or post, all of which parts maybe of any ordinary or suitable construction, according to the style ofchair desired, and therefore the chair illustrated in the drawings isonly typical of many different constructions or forms of chair to whichmy invention may be applied.

The chair is provided with a chair-arm 4, which may be of anyconstruction suitable for the purpose in hand and is pivoted at its rearend to the chair-back through the me dium of a suitable pivot-pin 5. Thechairarm' is adapted to rise and fall in a vertical plane for thepurpose of actuating the mechanism which causes the carrier bearing theadvertising cards, signs, or other matter to travel whenever thechair-arm is depressed. The advertising-carrier and the operatingmechanism therefor are designed to be arranged in the outer end portionof the chairarm, and for this purpose I prefer to provide a casing orhousing 6, havinga sight-opening containing a glass or other transparentmedium 7 and secured to or forming part of the chair-arm 4. The casingor housing renders it possible to operatively assemble the mechanismtherein and to subsequently attach the same to the chair-arm, but forthe purposes of my invention the casing may be regarded as ICO a part ofthe chair-arm, as obviously the chair-arm could be constructed in anysuitable manner with a chamber or compartment in its outer end portionfor receiving the carrier and its operatingmechanism, hereinafterexplained.

The carrier on which the advertising-cards, signs, or otheradvertisements are placed is in the form of a web 8, of flexiblematerial, having one end secured to the periphery of an unwinding-roller9 and its other end sooured to the periphery of a winding-roller 10.

I term therollers 9 and 10, respectively, unwinding ant winding rollersto more clearly distinguish them and to enable the invention to be moreclearly understood from the written description, as will hereinafterappear.

The unwinding-roller 9 is hollow or in the form of a tube and isrotatably mounted 011 a non-rotary shaft 12, having its ends secured inthe walls of the casing or housing 6. The hollow or tubular rollercontains a helical or spiral spring 13, which is attached at one end tothe non-rotary shaft and at the other end to the roller for a purposewhich will hereinafter appear.

The winding-roller 10 is mounted on a shaft 14,1'otatably mounted in thecasing or housing.

The rollers 9 and 10 are of a length approximately coextensive with thewidth of the advertisingnveb 4E, and preferably the length of therollers slightly exceeds the width of the web.

As shown in Fig. 4, the bottom wall of the casing is constructed with apendent tubular extension 15, slidably arranged over the upper end of anarm or lug 16, mounted on the upper end of the leg-frame or front post 3of the chair in such manner that the outer end portion of the chair-armcan rise and fall to a limited extent on the arm or lug, so that whenthe chair-arm is depressed the arm or lug will actuate a lever 17, whichis geared with and serves to transmit motion to the windingroller 10 forthe purpose of winding the advertising-web thereupon and unwinding itfrom the roller 9. The lever 17 is approximately semicircular in outlineand is constructed with a tailpiece, which overhangs the upper end ofthe arm or lug 16, and with a curved toothed portion, which constitutesa segmental gear 18. The actuating-lever is mounted at or near itscenter upon a shaft or stud 17*, extending from one wall of the casingor housing 6, and the segmental gear 18 meshes with the teeth of apinion 19, mounted on a shaft or stud 20.

The pinion 19 is attached to or forms part of a disk 21, provided with apivoted pawl 22, having a tailpiece 23 and an acting end 21 to engagethe teeth of a ratchet-wheel 25, attached to 01.- forming part of aspur-gear or gear-wheel 26, mounted on the shaft or stud 20. Thegear-wheel 26 engages the teeth of a pinion 27, keyed or otherwisesecured to the shaft 14 of the winding-roller 10, so that if 'rotarymotion is imparted to this pinion the shaft and roller will likewise berotated. The pinion 27 is arranged on the shaft 14 at some distance fromone end of the roller 10, as will be seen by reference to Fig. at.

It will be obvious that when the chair-arm is depressed the tail end ofthe lever 17 is elevated by the action of the arm or lug 16, the pinion19 and disk 21 are rotated in the direction of the arrow, Fig. 5, andthe pawl 22, carried by the disk 21, rotates the ratchetwheel 25 andgear-wheel 26, which latter turns the pinion 27 in the direction of thearrow, Fig. 5, thereby correspondingly turning the roller 10, so thatthe advertising-web 4 is wound on this roller and unwound from theunwinding-roller 9.

\Vhen the pressure on the chain-arm is re leased, so that it can rise, aspring 28 will act to restore the actuating-lever 17 to its normalposition, Fig. 3, and at the same time raise the chair-arm. Owing to thepresence of the ratchet-wheel 25 and pawl 22 the movement of theactuating-lever to normal position is rendered possible withoutimparting rotary motion to the roller 10. This roller is, however,positively prevented from turning backward, except as hereinafterexplained with reference to the reversing mechanism, through the mediumof a pawl 29, mounted at one end on a pivot-pin 30, and having its otherend adapted to lie in the path of a pin 31, secured to and extendingfrom one end of the roller 10. hen this pawl 2 9 is in its normalposition, as shown in Fig. 3, its free extremity lies behind the pin 31,and obviously the roller 10 cannot turn backward.

The individual advertising cards or signs on the web are eachapproximately equal to the circumference of the winding-roller10, sothat each revolution of this roller moves the web the distance requiredto place a card or sign under the sight-opening containing the glass orother transparent medium '7, through which the card or sign is visibleand can be read by the person occupying the chair.

These remarks apply under the presumption that different advertisingcards or signs are placed upon the web, but obviously a singlecontinuous advertisement can be placed upon the web or upon a portionthereof, and the chair-arm operated to move the web, so that by repeatedoperations of the chair-arm the entire advertisement can be caused totravel under the glass or other transparent medium through which theadvertisement may be read.

7 hen the web is nearly or entirely unwound from the unwinding-roller 9and wound upon the winding-roller 10, the traversing motion of the webshould be reversed, so that it will then be unwound from the windingrollerand wound on the unwinding-roller. This is accomplished throughthe medium of reverswhen the latter will be stopped at the time itcompletes a revolution.

The device for tripping the pawl is composed of a duplex armed orbifurcated tripping-lever 32, havingan elastic or spring-tailpiece 33,and its two arms or members 34 and 35, preferably made of unequallength, the arm 35 being the longest and constructed or provided at itsextremity with a lateral stud 36, preferably formed by bending orturning the extremity of the arm 35 in a direction laterally toward oneend of the roller 10, as best seen in Fig. 4, so that the stud isadapted to be acted upon, as hereinafter explained, by a pin 37,extending from a reversing pinion 38, which is mounted on a stud-shaft38".

- The arms or members of the tripping-lever 5 are provided,respectively, with trippinglugs or-teeth 34 and 35 for tripping the pawl22 into and out of engagement with the ratchetwheel 25, as hereinafterexplained.

The pinion 27 is provided with a lateral pin 39, which at the completionof each revolution of the pinion engages one of the teeth of thereversing-pinion 38, so that for every revolution of the pinion 27 thepinion 38 advances one step or the space of one tooth.

The teeth of the pinion 38 are engaged by the free extremity of aleaf-spring 40, which permits the pinion to be forcibly rotated, butprevents it from being accidentally moved. The pinion 38 is constructedwith a number of teeth, the same as the number of the advertising cardsor signs or card-spaces provided on the web 8.

The engagement of the pin 37 on the pinion 38 with the stud 36 of thetripping-lever 32 is designed to occur at the time that the web reachesthe end of its travel in either direction. It will be obvious that whenthe pinion 38 is rotated in the direction of the arrow thereupon in Fig.3, and the pin 37 strikes the stud 36 of the tripping-lever, the longarm 35 of the latter will be elevated and the lug or tooth 34 on theshort arm 34 will be raised out of the path of the tail 23 of the pawl22, while the lug or tooth 35'" on the arm 35 of the trip-lever willbemoved into the path' of the tail of the pawl, in consequence of whichthe pawl will be tripped and thrown out of engagement with theratchet-wheel 25. It is now possible for the motion of the roller 10 tobe reversed for the purpose of reversing the motion of theadvertising-web.

WVhen the arm 35 of the tripping-lever is elevated by the pin 37 of thepinion 38, as above explained, the elastic tailpiece 33 of the leverlies in engagement with the trip-lever-retaining block 41, which issecured in a fixed position to one of the walls of the easing orhousing. This retaining-block 41 is constructed with tworeversely-inclined surfaces '42 and 43. When the tripping-lever is inthe position shown in Fig. 5, the tailpiece 33 engages the upperinclined surface 42, and when the trip-lever is operated on by the pin37 to lift the arm 35 of the lever the tailpiece 33 engages the inclinedsurface 43 of the re-' taining-block. By this means the trippinglever isretained in either position to which shifted; but at the same time itcan be operated by the action of the pin 37 on the stud 36.

The reversing-pawl 22 is acted upon by the free extremity of aleaf-spring 44, so conthis lever will act against the under side of thepawl 29 and raise its free end out of thepath of the pin 31 on-the endof the roller 10. At this instant the helical orspiral spring 13 rotatesthe roller 9, and a stop-finger 46, eX- tending from the pawl 29, ismoved into the path of the pin 31, so that when the roller 10 has made acomplete revolution the pin 31 will strike the stop-finger 4G and arrestthe roller. The stop-finger 46 will hold the pin 31 so long as thechair'arm is held depressed, but when the chair-arm is released the pawl29 will fall by gravity, and the pin 3l will pass over the extremity ofthe finger 46 and strike the extremity of the pawl 29. The parts are nowin position for a subsequent operation, which is carried int-o effect bydepressing the chair-arm, whereupon the operation last above describedis repeated, so

that by repeatedly depressing and releasing the chair-arm theadvertising-web 8 is unwound from the winding-roller 10 and wound uponthe unwinding-roller 9, and when the web is nearly or entirely unwoundfrom the roller 10 the pin 37 of the pinion 38 strikes the stud 36 onthe long arm of the trippinglever, thereby depressing this arm 35 andcausing the lug or tooth 34 on the arm 34 to move into the path of thetail 23 of the pawl 22, so that the acting end of the latter is i throwninto engagement with the ratchetwheel 25, in consequence of which thereverse motion of the advertising-web is provided for,

and the depressions of the chair-arm will time to depress the arm 35 ofthe tripping lever and at another time will elevate this arm of thetripping-lever, so that the lugs or teeth 34 and 35 on the arms 34 and35 of the lever are alternately thrown into and out of the path of thetailpiece on the pawl which is designed to engage and disengage theratchet-wheel of the spur-wheel or gearwheel which meshes into thepinion on the shaft of the winding-roller.

In the operation of the mechanism the pin 37 of the reversing-pinion 38never actually passes by the stud 36 on the arm 35 of the trippinglever; but, on the contrary, the pinion 38 immediately reverses itsdirection of motion after the pin 37 presses against the stud 36sufficiently to move the same the distance required to throw either ofthe lugs or teeth 34: and 35 into or out of the path of the tail 011 thepawl of the ratchet-Wheel.

The mechanism described is novel, simple, and efficient, and enables theadvertisingweb to be moved in one direction a predetermined time andthen automatically reversed to move in the opposite direction, so thatthe advertisements provided on the web can be repeatedly exposed to viewthrough the glass or sight opening in the upper side of the chair-arm.

It is desirable that the individual cards or signs provided on the webbe placed somewhat farther apart toward the end portions of the web inorder to compensate for the increasing circumference of the rollers asthe web winds upon either one of them, for the purpose of causing all ofthe cards or signs to be properly presented to view through the glass orsight opening.

The helical or spiral spring 13 tends to rotate the roller 9 in thedirection to wind the web on this roller, and when the roller 10 isrotated to wind the web thereupon the draft of the web rotates theroller 9 in opposition to the force of the spring 13, thereby windingthe spring and placing it under the required tension for the subsequentrewinding of the web on the roller 9 when the reversing mechanismoperates to permit the reverse motion of the parts.
